JOSEPH G. DUCK, OF MILWAUKEE, WISCONSIN, ASSIGNOR OF ONE-HALF TO JOHN G. THOMPSON, OF MILWAUKEE, VISCONSIN.

STEAM-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 756,943, dated April 12, 1904.

Application flied August 21, 1902.

To al?, whom, t mel/'y concern:

Be it known that I, JosnrH G. DUCK, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Steam-Separators, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

The main objects of this invention are to e'ectively separate water, oil, or other liquid from live or exhaust steam; to avoid condensation, reduction of live steam-pressure, or increase of back exhaust steam pressure; to break up the steam and bring all its particles into contact with metal, without which perfect separation cannot be effected; to conduct the water, oil, or other liquid out of the direct course'of the steam immediately upon its separation therefrom, and thereby prevent its reuniting lwith the steam, and generally to improve the construction and operation ofthe class of apparatus to which the invention pertains.

It consists in certain novel features of construction and in the arrangement and combinations of parts hereinafter particularly described, and pointed out in the claims.

In the accompanying drawings, like letters designate the same parts in the severalgures.

Figure 1 is a horizontal section on the line l l, Fig. 3, of a separator embodying the invention. Fig. 2 is a vertical cross-section of the same on the line 2 2, Fig. l; and Fig. 3 is a vertical longitudinal section at right angles to the sections shown in Figs. l and 2.

a is a casing, 'preferably cast in one piece in the form of a vertical cylinder having a rounded top and open bottom. Near the top this cylinder is formed on opposite sides with ianged pipe-couplings, which constitute the steam inlet and outlet connections b and c. Between these connections the chamber is provided with vertically and transversely disposed balile-plates cl, e, and f, which may be and are preferably cast integrally, with the casing a. They extend from the top of the casing to points a short distance below the Serial No. 120,468. (No model.)

inlet and outlet connections and c. All the plates are preferably vertically ribbed and grooved or corrugated on their front faces presented toward the inlet connection the outer or marginal ribs or corrugations ex tending beyond the others, as shown in Fig. l. The first and last plates CZ and f next to the inlet and outlet connections are centrally located and curved horizontally from their side edges toward the inlet connection, their curvature corresponding with the curvature of the cylindrical casing, and vertical spaces or openings being' left at their sides for the passage of steam. The intermediate plates c e are preferably located in a central transverse plane on opposite sides of the separatorchamber,with a central vertical space or opening between them for the passage of steam.

g g are sheet-metal plates held at their side edges by inturned vertical flanges 71, behind the several bande-plates and forming or inclosing therewith vertical passages or spaces 11 a', which open at the lower edges of said plates into the lower part of the separator,- chamber. These plates g are centrally supported by vertical ribs j' on the backs of the baflie-plates, and these ribs are formed at their lower ends with lugs It, over which said plates g are sprung into place and by which they are securely held in their proper positions.

Each of the several baflie-plates is formed at intervals from top to bottom with transverse passages Z Z, extending obliquely downward from front to back into the vertical passage or space between it and the adjacent deecting-plate g.

The separator, which is formed withan opening at the bottom, may be attached to an automatic trap in communication therewith, or the bottom may be closed by a plate .bolted to the casing a, and the water, oil, or other liquid collecting in the lower part of the separator-chamber may be drawn off from time to time through a valve-controlled dischargepipe, which is not shown.

The separator herein shown and described operates as follows: Steam entering through the inlet connection strikes the corrugated face of the first baffle-plate, by which it .is deiiected outwardly toward the sides of the separator-chamber and separated into two streams or bodies. Passing through the openings at the sid es of the iirst battle-plate, the two bodies or currents of steam strike the corrugated faces of the intermediate baiie-plates e e, by which they are deiiected inward and reunited. Passing thence in one body through the central opening between the inner edges of the plates e, the steam strikes the corrugated face of the last baille-plate f and is again deflected outwardly and separated into two streams orVV bodies. Passing through the openings at the sides ofthe plate f, these two streams or bodies again unite and pass out togetherthrough the outlet connection c, as indicated by arrows'in Fig. 1. The water, oil, or other liquid deposited on the bathe-plates is drawn with a portion of the steam through the oblique passages Z into the vertical spaces c', in which it is conducted down out of contact with the main body of steam into the lower part of th separator-chamber.

In passing through the separator the steam is broken up and brought into contact with extended metal surfaces on which the liquid entrained therewith is deposited, and the liquid thus separated is immediately conducted olif1 out of contact with the main body of steam, and thus prevented from reuniting therewith. The device as herein shown and described is extremely simple in construction, consisting of very few parts, and while it is very effective in operation it can be made at a comparatively small cost. The sheet-metal plates g can be readily removed and replaced for the purpose of cleaning the baHe-plates andl interior of the separator. A

Various changes in minor details of construction may be made within the spirit and intended scope of the invention.

I claiml. A steam-separator consisting of a chamber having steam inlet and outlet connections and a vertically-disposed baffle-plate arranged between the inlet and outlet transversely thereto and having oblique passage-ways extending downwardly through it from front to back and formed on the back with lugs, and a sheetmetal plateV sprung over and supported by said lugs to form a space ope'ning at the bottom into the lower part of said chamber, substantially as described.

2. A steam-separator consisting of a chamber having inlet and outlet connections on opposite sides and verticallydisposed baffle plates arranged transversely between said connections 'and having vertically corrugated front faces and oblique passages which extend downwardly through them from front to back into vertical spaces opening at their lower ends into said chamber, substantially as described.

3. A steam-separator consisting of a chamber having inlet and outlet connections on opposite sides and staggered baille-plates extending partially across said chamber and having oblique. passages extending downwardly through them from front to back into vertical lspaces which open below into said chamber,

substantially as described.

4. A steam-separator consisting of a vertically-disposed cylindrical chamber having inlet and outlet connections on opposite sides, vertically-disposed and centrally-located baffle-plates curved toward the inlet connection and intermediate side bali-le plates having oblique passages extending downwardly through them from front to back into vertical spaces which open below into said chamber, substantially as described.

5. A steam-separator consisting of a chamber having horizontally-disposed inlet and outlet connections on opposite sides, and vertically-disposed and centrally-located baffleplates and intermediate side baiiie-plates extending from the top of said chamber and terminating between the bottom and said inlet and outlet connections, said plates having oblique passages extending downwardly through them from front to back into spaces which open below into said chamber, substantially as described.

6. A steam-separator consisting of a chamber having-steam inlet and outlet connections on opposite sides, vertically-disposed horizontally-curved bafiie-plates arranged centrally opposite said inlet and outlet connections-with openings between them and the side walls of said chamber, vertically-disposed side baffleplates arranged between said curved plates on opposite sides of said chamber with anvopening between their inner edges, said plates being vertically corrugated ontheir front sides and having oblique passages extending downwardly through them from front to back, and vertical plates inclosing at the backs of said bathe-plates spaces which open into said chamber below, substantially as described.

In witness whereoirl I hereto aix my signature in presence of two witnesses.
